The MyRIAM personal dosimeter measures inhalation dose from long‑lived alpha and beta nuclides (LLRD) by drawing air through an internal pump and collecting aerosols on a small membrane filter for alpha spectroscopy and beta counting, with full compensation for natural radon daughters. Its 300 g, phone‑sized metal housing integrates the sampling head, battery, and electronics, allowing comfortable wear without cables. Dangerous dose levels trigger an audio‑visual alarm within 60 seconds, and the backlit display shows current dose and count rates. The rechargeable battery runs for about 24 hours and recharges in one hour, with only routine filter changes needed. A built‑in data logger records dose history, and data can be transferred to a PC via infrared; analysis software and the IR adapter are included.

SARAD

SARAD was founded in 1993. The company started as service provider assessing radioactive polluted properties with regard to their later decontamination. After a short time, the company started to develop electronic measuring instruments. In 1994, SARAD launched their first radon monitor. Since 1997, the development and manufacturing of premium measuring equipment have become the pillars the company is built on. Due to its positive business performance, the company was able to move into its own corporate building in 2000. Step by step the range of products has been extended over the following years.
